Both ends of the hot water supply pipe 20 and the cold water supply pipe 21 are provided with collars 20a and 21a respectively so as to have O rings 22 fitted outward one-side ends are fixedly inserted in mounting legs 23 fixed on both sides of the pedestal 10, and the other-side ends are inserted in the tap main body 11 in the center of the pedestal 10 so as to be fixed from the bottom by a supporting board 25. In this constitution, the tap is sealed by O rings 22 and positioned by the collars 20a, 21a, its center is fixed by the supporting board 25, both sides are fixed by the legs 23 fixed on the pedestal 10 so as to be prevented from being pulled off the pedestal 10 may be a simple constitution without a bottom plate, and the tap can be assembled only by inserting pipes and fixing with screws.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure from a pedestal portion to a main body of a single lever mixing stopper capable of mixing water and hot water and adjusting the amount of water discharged by one lever.

[0002]

2. Description of the Related Art Conventionally, a structure in which a water supply pipe and a hot water supply pipe are connected to a pedestal and the pedestal is connected to a main body of a mixing stopper has been known. For example, the actual exploitation Sho 62-13897
No. 3 and Japanese Utility Model Laid-Open No. 63-48068. As shown in FIG. 5, these accommodate the hot water supply pipe 2 and the water supply pipe 3 in the pedestal cover 1, one end is fixed to the plug body 4, and the other end is fixed to the mounting legs 5 and 5. The bottom surface of the pedestal cover 1 was covered with the bottom plate 6.

[0003]

However, the ends of the water supply pipe for hot water and the water supply pipe for hot water have plug bodies 4 and mounting legs 5 respectively.
Since 5 must be soldered or fixed with silver braze, it takes time to assemble, and since the bottom plate 6 is attached,
The number of parts increased and the cost increased. Therefore, in order to reduce the number of assembly steps, the connection between the water supply pipe for hot water and the water supply pipe for hot water is changed to reduce the cost.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a hot and cold water supply pipe and a mixing tap for joining hot water and water by a tap main body located on the center of the pedestal from the water supply pipe. , The flanges are provided at both ends of the hot water supply pipe and the water supply pipe, and the O-rings are externally fitted, one end is inserted and fixed to the mounting legs fixed to both sides of the pedestal, and the other end is inserted into the plug body at the center of the pedestal. However, it is fixed by a support plate from the bottom.

[0005]

With the above construction, the O-rings are fitted on both ends of the hot water supply pipe and the water supply pipe,
Insert one end into the mounting leg, insert the other end into the stopper body and insert until it hits the collar, seal with O-ring, position with collar, and fix the center with the support plate,
Both sides are fixed by legs fixed to the pedestal to prevent the pedestal from coming off, and the pedestal may have a simple structure without a bottom plate, and assembling may be performed by inserting a pipe and fixing with a screw.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved and the means for solving the problems of the present invention are as described above. Next, the embodiments shown in the accompanying drawings will be described. FIG. 1 is a side sectional view of a single lever mixing plug, and FIG. Similarly, an assembled perspective view, FIG. 3 is a rear perspective view of the base,
FIG. 4 is a partial cross-sectional view of a front view of a water supply pipe and a mounting leg connecting portion.

To explain the overall structure in FIGS. 1 and 2, the pedestal 10 is formed by die casting of zinc or the like, and a cylindrical fitting portion 10 into which the plug body 11 is fitted at the center of the pedestal 10.
a is formed, the lower portion of the plug body 11 is fitted into the fitting portion 10a, the water discharger 12 is externally fitted to the plug body 11, and the water discharge port 12a is projected and communicated in front of the water discharger 12. A cap 17 is externally fitted on the water discharge body 12, and a lever handle 15 is provided on the cap 17.
5 A sliding body 16 is fixed at the center of the lower end, and the sliding body 16 is provided with a protrusion at the lower end to fix the fixed valve body 13 on the plug body 11.
The movable valve body 14 is fitted over the movable valve body 14 and is rotated by rotating the lever handle 15, so that the movable valve body 14 slides on the fixed valve body 13 to adjust the discharge amount and the mixing amount of water and hot water. It is adjustable.

The plug body 11 includes a hot water passage 11a and a water passage 1
1b penetrates in the left-right vertical direction, and the mixing passage 1 is formed in the center of the upper surface.
1 c is formed up to a midway portion in the vertical direction and communicates with a water discharge passage groove 11 d formed on a side surface, and the water discharge passage groove 11 d is formed.
Is configured to communicate with the water discharge port 12a of the water discharge body 12 shown in FIG. 1 when assembled. And the hot water passage 11a
The hot water supply pipe 20 and the water supply pipe 21 are connected to the lower end of the water passage 11b.

The hot water supply pipe 20 and the water supply pipe 2
1 has one side bent into an L-shape, and both ends are subjected to brim processing to form collar portions 20a and 21a.
The O-ring 22 is fitted on the end side of the hot water passage 1a.
1a and the lower end of the water passage 11b and the mounting legs 23, 23 are inserted. That is, as shown in FIG. 4, the ends of the hot water supply pipe 20 and the water supply pipe 21 are fitted with the O-rings 22 and the connecting portions 23a of the mounting legs 23 (or the lower ends of the hot water passage 11a and the water passage 11b). The O-ring 22 provides a seal just by inserting it into the connector, and the connection work is simplified without the need for welding or screwing.

Fixing pieces 23b, 23b for fixing to the pedestal 10 are projected on the upper part of the mounting leg 23 to open screw holes, and screws 24, 24 are provided on the back surface of the pedestal 10 as shown in FIG. The pedestal 10 can be fixed to the screw holes 10b and 10b, and the inside of the pedestal 10 has a strength that can withstand the lateral stress at the time of fixing in accordance with the shape of the mounting leg. 13 also has screw holes 10c
Support plate 25 for holding the water supply pipe by providing 10c
Can be fixed from the back side with screws 26, 26 ..., and the support plate 25 is provided with semicircular cutouts 25a, 25a on both sides of the upper surface in accordance with the shape of the water supply pipe.
The flange portion of 21 is pressed and a screw hole 25b is opened in the center so that it can be fixed to the plug body 11 with a screw 27 so that the water supply pipes 20 and 21 cannot be pulled out.

A connection screw portion 23c is provided on the lower portion of the mounting leg 23, and a circular sponge 30, a chrysanthemum seat 31, and a tightening nut 33 are externally fitted to the connection screw portion 23c to internally mount a check valve. The socket 34 is configured to be connected.
Therefore, since the check valve is a separate body from the mounting leg 23 and the water supply pipe and is not unitized with the pedestal 10,
It can be easily attached and detached, and maintenance can be done easily.

[0012]

Since the present invention is configured as described above, it has the following effects. That is, the pedestal of the single lever type mixing stopper and the water supply pipe can be easily assembled, the working time can be shortened, the number of parts can be reduced by omitting the bottom plate, and the fixing does not need soldering or silver brazing. Therefore, the cost can be reduced, and the disassembly can be easily performed, so that the workability of maintenance can be improved.
